Beach Care Project. Evento di divulgazione scientifica sulla raccolta e differenziazione dei rifiuti solidi urbani sul litorale di Capaci nell’ambito del progetto 4Elements
Get PDFNel mese di novembre 2021 è stata organizzata un’operazione di beach cleaning presso la spiaggia del comune di Carini vicino Palermo dal nome “Beach Care Project”, in collaborazione col comune e diverse associazioni ambientaliste sul territorio come LiberAmbiente, Muoversi a Carini, Plastic free e Proloco. L’obiettivo dei due giorni di lavoro in programma sono stati, oltre alla rimozione di rifiuti di ogni genere dal litorale interessato, la divulgazione scientifica e un’azione di formazione condotta dagli esperti CNR con gli scolari partecipanti sui temi della sostenibilità ambientale, la raccolta differenziata dei rifiuti e la protezione dell’ambiente ponendo l’accento sul concetto di condotta civica “green” a 360°. All’evento è intervenuto un elicottero del N.O.E. dei Carabinieri e tutta l’operazione è stata condotta con l’ausilio di una pala meccanica per la raccolta dei rifiuti pesanti messa a disposizione del partner del progetto “CNH Industrial”
Concreti e dividui. Il lessico filosofico di Gilberto di Poitiers
Get PDFQuesto libro è un’indagine intorno al lessico filosofico di Gilberto di Poitiers, fine metafisico vissuto in Francia tra 1085 circa e 1154, e ai testi nei quali il suo pensiero si manifesta. Nella inesauribile complessità della loro concretezza, per Gilberto tutti gli individui — umani, animali, vegetali — sono tanto singolari e diversi gli uni dagli altri quanto ineludibilmente connessi da rapporti di condivisione formale: nodi di una immensa rete di stati e riflessi più che una pluralità di sostanze per sé stanti. Il linguaggio, nelle sue diverse modalità espressive, insieme seziona e riflette tale intricata trama. Il volume esamina in particolare i commenti gilbertini al De trinitate e al De praedicatione trium personarum di Boezio. La prima parte li percorre paragrafo per paragrafo, cercando di chiarificare il non sempre evidente discorso di Gilberto e il suo ricorso alla tradizione, soprattutto logica e retorica. È poi proposta una traduzione in italiano dei due commenti, correlata, tramite collegamenti interstestuali, all’edizione latina di Nikolaus M. Häring. La seconda parte del libro è consacrata al trattato anonimo Invisibilia Dei, anch’esso proposto in traduzione italiana connessa al testo latino. Lo scritto, risalente probabilmente alla seconda metà del XII secolo, riprende il lessico speculativo gilbertino ma semplificandolo e fornisce così una via d’accesso relativamente agevole al pensiero del maestro. Chiude il volume, nella terza parte, una bibliografia degli studi sulla filosofia di Gilberto di Poitiers
Dysphagia as a Rare Presentation of Cervical Cancer with Mediastinal Metastasis
Get PDFDysphagia has a broad aetiology and so it is essential to identify the precise cause. Cervical cancer metastasis is distinctive in that it usually involves local lymph node invasion; however, approximately 1% of cases have mediastinal involvement, which can cause severe compressive symptoms in rare situations. To highlight an uncommon severe manifestation of cervical cancer relapse, we describe a case of dysphagia in a woman with a history of cervical cancer. After a thorough investigation that included endoscopy, endoscopy with ultrasound, an oesophagogram and fine needle aspiration, we eventually reached the diagnosis of mediastinal metastatic cervical cancer. Following interventions, the patient's condition gradually improved, both clinically and radiographically
Alkaline Diuresis as Treatment for 2,4-D Dimethylamine Herbicide Intoxication
Get PDFAcute intoxication with 2,4-D dimethylamine is rare, often fatal and can cause signs and symptoms in different organ systems. This case report describes the effectiveness of alkaline diuresis as a life-saving treatment for chlorophenoxy intoxication, especially in healthcare facilities without access to haemodialysis. A patient had attempted suicide by ingesting 2,4-D dimethylamine, with toxic effects on the central and peripheral nervous systems, and the gastrointestinal and respiratory systems. However, she significantly improved after alkaline diuresis, accompanied by resuscitation, decontamination of the gastrointestinal system, and supportive therapies
Hydropneumopericardium: A Rare Complication of an Oesophageal Tumour
Get PDFHydropneumopericardium is a rare event with a risk of serious complications. Timely diagnosis and treatment is important as it can improve prognosis. We report the case of a 77-year-old male patient who presented with acute interscapular pain which developed during a meal. An oesophago-pericardial fistula was found in the context of malignant oesophageal disease
Tuberculosis Presenting as Acute Sepsis and Secondary Hemophagocytic Lymphohistiocytosis
Get PDFWe report the case of a 61-year-old man admitted to our emergency department with fever. At admission, he was hypotensive and tachycardic. In the initial investigation, elevation of inflammatory parameters, acute kidney injury (Kidney Disease Improving Global Outcomes (KDIGO) 3), hyperbilirubinemia, and hepatic cytocholestasis were evident. Empirical antibiotic therapy was started, after sepsis was assumed without an identifiable cause. His condition took an unfavorable clinical course, with respiratory failure, hepatosplenomegaly, pancytopenia, hyperferritinemia and hypofibrinogenemia. Microbial culture studies and a general immunological study were negative and lymphoproliferative disease was therefore excluded. Bone marrow aspirate revealed hemophagocytosis without granulomas. A diagnosis of hemophagocytic lymphohistiocytosis was assumed and pulse methylprednisolone therapy initiated. As this resulted in only a transient improvement, immunoglobulin and rituximab were initiated as a second-line therapy. The patient sadly had an unfavorable outcome despite all measures undertaken. In the postmortem study, Mycobacterium tuberculosis complex was isolated in the bone marrow aspirate, which led to the postmortem diagnosis of disseminated tuberculosis and angioinvasive pulmonary aspergillosis. The clinical presentation of disseminated tuberculosis is non-specific and hemophagocytic lymphohistiocytosis is one of its rare presentations. The mortality rate of hemophagocytic lymphohistiocytosis is high and increases with delayed diagnosis of the underlying condition and respective treatment
Herbal Teas and Thrombocytopenia: A Curious Case of Yellow Dock and Burdock-Induced Thrombocytopenia
Get PDFImmune thrombocytopenia (ITP) is a bleeding disorder characterized by a decreased number of platelets. It is an immune system-mediated condition, with formation of antibodies against a structural platelet antigen. Although the pathogenesis remains elusive, primary disease is idiopathic and comprises 80% of cases. However, quite a few secondary causes have been established including Helicobacter pylori, varicella-zoster virus and cytomegalovirus. A few cases with an incidental association with herbal medications have been reported, but this causality has not been studied in detail.Here we present the case of 38-year-old African-American woman who presented with symptomatic thrombocytopenia, with a platelet count of 5 K/μl 1 week after she had consumed herbal tea containing Rumex crispus (yellow dock) and Arctium lappa (burdock). The association between unstudied herbs and ITP needs further research, given the widespread use of these substances and ongoing public uncertainty about their benefits
Acute Compartment Syndrome in the Setting of Weight Loss Supplements and Exercise-Induced Rhabdomyolysis
Get PDFThe growing prevalence of obesity in the USA has resulted in increased consumption of weight loss products that promote fat metabolism. Dietary supplements used for weight loss contain a wide variety of ingredients but the amount of scientific information available on these ingredients varies considerably. Such supplements have documented and undocumented adverse effects. Although the FDA frequently issues health advisories, the health consequences of consuming supplements are often overlooked by the general public. A common supplement used for weight loss is Hydroxycut. The ingredients used in the different forms of Hydroxycut products vary but generally include caffeine and green tea extract, which are responsible for a wide range of adverse effects. We present the case of 41-year-old man with a medical history of polysubstance abuse who developed acute compartment syndrome in the setting of rhabdomyolysis from prolonged immobilisation and the use of Hydroxycut. This case demonstrates the possible adverse effects of consuming weight loss herbal supplements like Hydroxycut. Healthcare professionals and consumers are encouraged to report serious adverse events or product quality problems with the use of these supplements to the FDA's MedWatch adverse event reporting program
Late Infective Endocarditis Associated with an Atrial Septal Defect Occluder Device
Get PDFThe Amplatzer septal occluder is one of several percutaneous devices used for the closure of secundum atrial septal defects. The main complications are related to the procedure, with infection being the least common. We present the case of a 67-year-old woman with a secundum atrial septal defect, who, 3 years after repair with an Amplatzer occluder, was admitted with sepsis and bacteraemia following recent hospitalization in an intensive care unit. Transoesophageal echocardiography showed the presence of a mobile echogenic structure in the left atrium suggestive of a vegetation. Few cases of late endocarditis involving the Amplatzer device have been reported, even though partial endothelization is one of the risk factors. There are no guidelines for the prevention, diagnosis or management of this complication
Form factors in quantum gravity: Contrasting non-local, ghost-free gravity and Asymptotic Safety
No full textForm factors constitute the key building block when organising the gravitational dynamics in terms of a curvature expansion. They generalise the concept of momentum-dependent couplings to curved spacetime. Moreover, they may capture modifications of the gravitational interactions at high energy scales in a non-perturbative way. We briefly review the role of form factors in various
quantum gravity programmes with special emphasis on non-local, ghost-free gravity and asymptotically safe gravity. In this context, we introduce a quantum gravity motivated scalar toy model, which demonstrates that Lorentzian asymptotic safety may be compatible with the causal propagation of gravitons
